Allison Expands Fuel-Efficient Medium-Duty Transmission Tech

Heavy Duty Trucking (HDT)  /  October 6, 2017

Allison Transmission has begun offering its xFE fuel-saving technology on two more of its medium-duty transmissions, including the 1000 Series and 2000 Series, the company has announced.

The xFE technology, which stands for extra fuel economy, can improve fuel efficiency by 7% when compared to baseline models. The technology was previously available on select 3000 Series models.

The 1000 Series and 2000 Series transmissions are usually paired with smaller medium-duty trucks and buses. They offer the same ratings as current models and incorporate a redesigned torque converter damper coupled with the FuelSense 2.0 Max package. The damper enables first range lock up and delivers significantly more lock up operation, according to the company. They operate at lower engine speeds in higher ranges to further improve fuel economy. The xFE transmissions are compatible with alternative fuel engines.

Allison debuted its xFE transmissions in 2015 for 3000 Series buses. FuelSense 2.0 with DynActive shifting debuted in March. Allison employs a series of software enhancements to provide a variable combination of shift points and learning algorithm that searches for the ideal balance of fuel economy and performance.

Allison transmissions also use Continuous Power Technology to smoothly multiple engine torque and deliver more power to the wheels.

Allison Transmission extends xFE fuel-saving to Series 1000, 2000

Green Car Congress  /  October 6, 2017

Allison Transmission recently announced availability of its latest fuel economy technology for its 1000 Series and 2000 Series at the North American Commercial Vehicle Show in Atlanta.

Referred to as xFE, designating extra fuel economy, the fully automatic bus and truck transmissions have demonstrated improvements up to 7% when compared to baseline models.

Other than our electric hybrid products, xFE models represent the very best fuel economy technology we offer. Our goal with this expansion of the xFE portfolio is to also now achieve the best fuel economy from an automatic transmission in smaller, medium-duty buses and trucks. The new design works to achieve enhanced fuel economy in start-stop dense, low average speed duty cycles. Transit and city buses are the ideal candidates for this technology and that’s why we’ve remained focused on those applications.

—John Coll, senior vice president of global marketing, sales and service for Allison Transmission

The 1000 Series and 2000 Series xFE transmissions have the same space claim and ratings as current models, but incorporate a redesigned torque converter damper coupled with the FuelSense 2.0 Max package. The damper enables first range lock up, delivering significantly more lock up operation and operating at lower engine speeds in higher ranges to further improve fuel economy. All xFE transmissions are compatible with alternative fuel engines.

First announced in 2015, xFE transmissions were exclusively available in the 3000 Series for bus applications. The new models represent the first expansion of the xFE portfolio and come standard with FuelSense 2.0.

Announced in March, FuelSense 2.0 with DynActive Shifting delivers additional fuel savings beyond original FuelSense software. Through a set of proprietary software enhancements, the new FuelSense 2.0 uses DynActive Shifting to provide an infinitely variable combination of shift points and uses a learning algorithm to continuously find the ideal balance of fuel economy and performance. Available in three packages, FuelSense 2.0 allows fleets to optimize fuel economy and performance to their specific needs.
